We are general mechanical electrical contractors specializing in residential and commercial applications your one stop shop for all your needs

"We hired this contractor almost a year ago to do various projects. The work was supposed to be finished in 10 days according to the contract. We are here almost a year later and there is still work that is unfinished. I paid Martin before all of the work was completed, and I can’t get ahold of him to finish the work now. The pipe still hasn’t been cut, and there is still a huge piece of concrete in our side yard. I’m not sure what to do now."

"I have lived in my house for two years, and have had problems with rooms that wouldn't get cool in the summer (despite central air conditioning), or stay warm in the winter. I had to move my bedroom after the first summer and winter, and could not comfortably sit for long in my living room. I replaced all my windows with triple paned ones in March 2020, which made little difference. I had PECO do an energy assessment of my home last spring. Home Energy & Comfort was on PECO's list of recommended contractors. I researched them further, and their reviews were impressive. I soon found out why. Gordon Clark, one of the co-owners, and a crew of three to four workers spent two days at my home in early June 2020. To make a long story short, they insulated everywhere that needed it (including the garage which is underneath my living room), air sealed gaps and cracks where needed, sealed up ducts, spray foamed rim and band-joist area, and did air seal blowing tests before and after the work. The team was always polite and respectful, and masked due to the Coronavirus. They protected everywhere they worked with plastic sheets and tarps, and cleaned up well afterward. They also did all the work to submit paperwork for rebates from PECO, and deducted the rebate amounts from my bill rather than have me wait for them. This has honestly been the best money I have invested in my home. The hot days have shown me the vast improvement in energy efficiency. I was able to move my bedroom back to the bigger room in the southwest corner, which is now very comfortable. An added bonus is the reduction of dust in my home. I am very happy I chose Home Energy & Comfort to do the work in my home!"

Energy Efficiency Auditing questions, answered by experts

Not all homes are suited for solar panel systems. Older roofs or those in poor condition may need repairs or replacement before solar panels can be installed. Some other factors to consider are the amount of sunlight your roof receives, the roof’s orientation and pitch, and any shading from nearby trees or buildings.

DIY is possible with basic tools. Professional audits provide comprehensive assessments and tailored recommendations.

Hawaii is currently rated as the most expensive state for utilities. How much are utilities for a house in Hawaii? With electricity costs in Hawaii totaling nearly 42 cents per kilowatt-hour, residents are paying more to run their households than any other residents. Electricity costs in Hawaii are so high, mostly due to the fact that most of the electricity available to residents is produced using oil that must be shipped in from other places.

Upgrade to double-glazed glass or apply energy-efficient coatings to reduce heat loss and utility costs.

You can check your home's humidity in a few ways. A simple option is to use a hygrometer, which you can find at a hardware or big box store. Your smartphone may also have an app that can measure humidity. Modern thermostats, particularly smart thermostats, are also able to measure humidity levels.
